区传递的2-(v,k,1)设计与射影辛群PSp_n(q)
Block transitive 2-(v,k,1) designs and projective symplectic groups PSp_n(q)
【摘要】 分类自同构群为射影辛群PSp_n(q)的区传递2-(v,k,1)设计,得到如下定理:设D为一个2-(v,k,1)设计,G≤Aut(D)是区传递,点本原但非旗传递的.若q为偶数且n≥14,则G(?) PSp_n(q).
【Abstract】 This article is a contribution to the study of the automorphism groups of 2-(v,k,1) designs.In particular,projective symplectic groups PSp_n(q) are studied and the following theorem is proved: Let D be a 2-(v,k,1) design,G≤Aut(D) be block transitive,point primitive but not flat transitive ,then G is not PSp_n(q),with q even and n≥14.
